[0010] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In all the drawings, the same components are given the same reference numerals and the description will be omitted as appropriate.

[0011] In the following description, each component of the mobile device 10 is represented as a functional block, not as a hardware configuration. Each component of the mobile device 10 is realized by any combination of hardware and software, centered on the CPU of any computer, memory, a program loaded into the memory, a storage medium such as a hard disk for storing the program, and an interface for network connection. There are various variations in the method and device for realizing the above.

[0012] 1 is a block diagram showing the configuration of a mobile device 10 according to an embodiment. The mobile device 10 is capable of realizing a first function and a second function different from the first function, and includes a first functional unit 110, a biometric information acquisition unit 120, a control unit 130 (which also serves as a second functional unit), and an environmental information acquisition unit 135.

[0013] The first function unit 110 causes the portable device 10 to realize a first function, and the control unit 130 causes the portable device 10 to realize a second function. The first function is different from both the function of acquiring biometric information and the function of processing the biometric information. The biometric information acquisition unit 120 acquires biometric information of the user of the portable device 10. While the first function unit 110 is executing the first function, the user of the portable device 10 is touching the portable device 10. Therefore, the biometric information acquisition unit 120 acquires the biometric information while the first function unit 110 is executing the first function. Then, the control unit 130 realizes the second function using the biometric information acquired by the biometric information acquisition unit 120.

[0014] The environmental information acquiring unit 135 acquires environmental information. The environmental information indicates an environment in which the biometric information acquiring unit 120 acquires the biometric information. The acquisition environment is, for example, a factor that affects the accuracy of the biometric information. The control unit 130 controls the biometric information acquiring unit 120 based on the environmental information acquired by the environmental information acquiring unit 135.

[0015] In the example shown in the figure, the portable device 10 further includes a display unit 140. The portable device 10 may be, for example, a portable communication terminal such as a mobile phone or a smartphone, a portable game machine, or a portable audio player. The portable device 10 will be described in detail below.

[0016] The first function that the first functional unit 110 causes the portable device 10 to perform is, for example, a communication function such as data communication or voice communication. Examples of data communication include e-mail communication and access to the Internet. Examples of voice communication include telephone communication. However, the first function may also be other functions, such as inputting or editing data, or viewing data stored in the portable device 10. Furthermore, if the portable device 10 has the functionality of a portable game device, the first function may also be playing a game.

[0017] The biometric information acquiring unit 120 acquires biometric information of a user who is touching the mobile device 10. The biometric information may be information about vital signs, or physical property values ​​such as impedance, sound speed, infrared absorptivity, or infrared reflectivity of the user's body. In the latter case, the control unit 130 calculates a value indicating the health level of the user from the physical property value (for example, bone age, skin age, muscle age, vascular age, or blood glucose level). The biometric information may also be information indicating the speed or accuracy of the user's input to the mobile device 10. In this case, the control unit 130 can calculate the user's brain age from the biometric information. As described above, the biometric information acquiring unit 120 acquires the biometric information while the first function unit 110 is executing the first function. The operation of the biometric information acquiring unit 120 is controlled by the control unit 130.

[0018] The control unit 130 realizes the second function by using the biometric information acquired by the biometric information acquisition unit. For example, the control unit 130 causes the display unit 140 to display the biometric information acquired by the biometric information acquisition unit 120 or a result of processing the biometric information (for example, at least one of the above-mentioned bone age, skin age, muscle age, blood vessel age, and brain age) at a timing when the first function unit 110 is not executing the first function.

[0019] As described above, the environmental information acquiring unit 135 acquires information indicating the environment in which the biological information is acquired by the biological information acquiring unit 120. The acquisition environment indicates, for example, factors that affect the accuracy of the biological information. Specifically, the acquisition environment indicates, for example, the body temperature of the living body, air pressure, whether or not a meal was eaten immediately before acquisition, whether or not the living body was active immediately before acquisition (including both physical activity and mental activity), or whether or not a bath was taken immediately before acquisition. The information indicating the acquisition environment is, for example, the body temperature of the living body, air pressure, the time of acquisition of the biological information, or the amount of input to the mobile device 10. This information is generated, for example, by a sensor, a microphone, or a clock included in the environmental information acquiring unit 135.

[0020] For example, if the information indicating the acquisition environment is the body temperature of a living body, the environmental information acquisition unit 135 has a temperature sensor. If the information indicating the acquisition environment is the atmospheric pressure, the environmental information acquisition unit 135 has a barometer. If the information indicating the acquisition environment is the acquisition time of the biological information (for example, to avoid a time when a person is likely to be taking a bath, or to avoid a certain time after a meal), the environmental information acquisition unit 135 has a clock. If the environmental information acquisition unit 135 has a clock, the time when acquisition of the biological information should be avoided is registered in advance in the memory unit of the mobile device 10.

[0021] The time period during which acquisition of biometric information should be avoided is registered in the storage unit of the mobile device 10, for example, in the following manner.

[0022] First, the mobile device 10 acquires data such as that shown in FIG. 22 every day for, for example, about one week. Then, by processing these acquired results, the time when a singular point (for example, a point that is more than a standard away from the average age) is likely to occur is recognized. Then, the recognized time is registered as a time when acquisition of biometric information should be avoided. In addition to the configuration for avoiding acquisition of biometric information at the singular points described above, for example, by processing the data shown in FIG. 22, it is also possible to actively acquire biometric information during a time period during the day when a relatively stable calculation result is obtained (when there is little change in the calculation result over time).

[0023] 2 is a flowchart showing an example of the operation of the portable device 10. When the user is operating the first functional unit 110, the user is touching the portable device 10. Therefore, the biometric information acquisition unit 120 can acquire biometric information of the user. Using this, when the control unit 130 detects that the first functional unit 110 is operating (step S10: Yes), The control unit 130 acquires environmental information from the environmental information acquisition unit 135. Then, based on the environmental information, the control unit 130 controls the biometric information acquisition unit 120 to acquire the biometric information (step S20) if the environmental information satisfies a predetermined condition (step S15: Yes). On the other hand, if the environmental information does not satisfy the predetermined condition (step S15: No), the control unit 130 does not allow the biometric information acquisition unit 120 to acquire the biometric information.

[0024] For example, when the environmental information is the body temperature of a living body, the control unit 130 acquires the biological information only when the body temperature is within a standard range. When the body temperature is outside the standard range (e.g., high), it is highly likely that the living body has just exercised or is sick. In such cases, the reliability of the biological information is reduced. For this reason, the control unit 130 does not allow the biological information acquisition unit 120 to acquire the biological information.

[0025] Moreover, when the environmental information is air pressure, the control unit 130 acquires the biological information only when the air pressure is equal to or higher than a criterion. Moreover, when the environmental information is time, the control unit 130 causes the biological information acquisition unit 120 to acquire the biological information only when the time satisfies a criterion (i.e., when it is assumed that the time is not after a meal and not after a bath).

[0026] The environmental information acquiring unit 135 may also have a hygrometer that measures the humidity of the skin of the living body. In this case, if the humidity of the skin is equal to or higher than a reference value, it is highly likely that the living body has just taken a bath, and therefore the control unit 130 does not allow the biological information acquiring unit 120 to acquire biological information.

[0027] Furthermore, when the measurement target of the biometric information acquisition unit 120 is the user of the mobile device 10, the environmental information acquisition unit 135 may acquire the presence or absence of input to the mobile device 10 as environmental information. For example, the control unit 130 judges whether the input to the mobile device 10 exceeds a standard. For example, when input to the mobile device 10 (including voice input in a telephone call (input to a microphone) and operation of the mobile device 10 (operation of a touch panel)) is continuously performed for a certain period of time or more, it is judged that the user's mental activity is vigorous, and the control unit 130 does not allow the biometric information acquisition unit 120 to acquire biometric information.

[0028] Furthermore, if the environmental information acquisition unit 135 has a microphone, the information indicating the acquisition environment may be the volume of the voice input to the microphone. In this case, the environmental information acquisition unit 135 may use a frequency filter or the like to extract only noise components and use the volume of the extracted noise as information indicating the acquisition environment. Then, if the volume of the voice satisfies a criterion (for example, if it is less than a criterion value), the control unit 130 causes the biometric information acquisition unit 120 to acquire the biometric information.

[0029] Furthermore, the environmental information acquiring unit 135 may have a temperature sensor for measuring the temperature of the user's finger. In this case, when the finger temperature acquired by the environmental information acquiring unit 135 satisfies a standard (for example, within a standard range), the control unit 130 causes the biometric information acquiring unit 120 to acquire biometric information.

[0030] Furthermore, when the biometric information acquiring unit 120 has a sensor that can be touched by the user (for example, the example shown in FIG. 20 described later), the environmental information acquiring unit 135 may further have a pressure sensor in the vicinity of this sensor. Then, when the detection value of the pressure sensor satisfies a standard (for example, within a standard range), the control unit 130 causes the biometric information acquiring unit 120 to acquire biometric information.

[0031] Next, the control unit 130 processes the information acquired from the biometric information acquisition unit 120 to generate data to be displayed on the display unit 140 (step S30). Then, the control unit 130 causes the display unit 140 to perform display. This display is performed to allow the user to recognize the biometric information or the processing result thereof (step S40). Note that the timing for this display is, for example, when the user inputs to the mobile device 10 that this display is to be performed. Also, this display may be performed automatically to alert the user when a significant change appears in the user's biometric information or when, for example, the age based on the biometric information (for example, skin age, bone age, or brain age) is greater than the actual age by a reference value or more.

[0032] As described above, according to this embodiment, the control unit 130 causes the biometric information acquisition unit 120 to acquire biometric information while the first function unit 110 is operating. This eliminates the need for the user of the mobile device 10 to perform an operation to acquire the biometric information. This reduces the burden on the user.

[0033] Furthermore, the biometric information acquiring unit 120 acquires the biometric information only when the environmental information detected by the environmental information acquiring unit 135 satisfies the conditions. Therefore, by appropriately setting the above-mentioned conditions, it is possible to prevent the biometric information from being acquired under specific conditions (for example, immediately after a meal, immediately after heavy physical or mental activity, immediately after a bath). Therefore, it is possible to measure the biometric information with high accuracy.

[0034] Furthermore, the control unit 130 causes the display unit 140 to display the biometric information acquired by the biometric information acquisition unit 120 or the result of processing the biometric information at a timing when the first function unit 110 is not executing the first function. Therefore, the user can recognize the biometric information acquired by the biometric information acquisition unit 120 or the result of processing the biometric information.

[0035] (Variation 1) 3 and 4 are flowcharts showing the operation of the control unit 130 according to the first modification. As shown in FIG. 3, when the control unit 130 according to this modification detects that the first functional unit 110 is operating (step S10: Yes), the control unit 130 causes the biometric information acquisition unit 120 to acquire biometric information and the environmental information acquisition unit 135 to acquire environmental information (step S22). Then, the control unit 130 stores the acquired biometric information and environmental information in a storage unit in association with each other (step S24). This storage unit may be provided inside the mobile device 10 or may be provided outside the mobile device 10. By performing the process shown in FIG. 3, the storage unit stores a plurality of combinations of biometric information and environmental information.

[0036] When it is time to process the biometric information, the control unit 130 reads out a plurality of combinations of biometric information and environmental information from the storage unit (step S31 in FIG. 4). The control unit 130 then selects a combination in which the environmental information satisfies a criterion from among these combinations, and generates display data using the biometric information included in the selected combination (steps S32 and S33). The display unit 140 then displays the results using the generated display data (step S40).

[0037] According to this modification, the control unit 130 generates display data using only the biological information for which the environmental information satisfies the conditions. Therefore, by appropriately setting the above conditions, it is possible to prevent the display data from including biological information acquired under specific conditions (for example, immediately after a meal, immediately after heavy physical or mental activity, immediately after a bath). Therefore, it is possible to measure the user's biological information with high accuracy.

[0038] (Variation 2) 5 is a diagram showing a portable device 10 according to the second modification together with its usage environment. In the portable device 10 according to this modification, the first function performed by the first functional unit 110 is a data communication function. The first functional unit 110 is connected to the information processing device 20 via the communication network 30. The information processing device 20 stores statistical data of biometric information or statistical data of the results of processing the biometric information. The control unit 130 acquires the statistical data via the first functional unit 110, and causes the display unit 140 to display the statistical data together with the biometric information acquired by the biometric information acquisition unit 120 or the results of processing the biometric information.

[0039] FIG. 6 shows an example of a screen displayed by the display unit 140 in this modified example. As described above, the display unit 140 displays the biometric information acquired by the biometric information acquisition unit 120 or the results of processing the biometric information together with statistical data. Therefore, the user can objectively recognize his / her own health condition. Note that in this figure, the data is displayed in a graph format, but the display format of the data is not limited to a graph. For example, the data may be displayed in a table format.

[0040] For example, in the example shown in FIG. 6, the control unit 130 calculates the age (hereinafter referred to as the estimated age) based on the biometric information. The statistical data includes regression data (e.g., a regression equation) showing the correlation between the estimated age and the actual age. The control unit 130 may convert the estimated age of the user of the mobile device 10 into the actual age corresponding to this age in the statistical data (hereinafter referred to as the actual age based on the statistical data) and display the actual age based on the statistical data on the display unit 140. In this case, the user can easily recognize where his / her estimated age is located relative to the national average. This conversion may be performed by an external device (e.g., the information processing device 20). The estimated age displayed on the display unit 140 may be corrected so that the slope of the linear regression equation of the actual age and the estimated age in the statistical data is 1. This correction is performed, for example, by using the regression data described above.

[0041] Alternatively, the ranking may be determined based on the magnitude of the difference between the estimated age and the actual age. In this case, the statistical data includes statistical information on the difference between the estimated age and the actual age. Then, the control unit 130 calculates the ranking of the user of the mobile device 10 according to this statistical information and causes the display unit 140 to display the ranking.

[0042] Furthermore, the information processing device 20 may store the results of a questionnaire conducted on users whose estimated age is lower than their actual age (who have successfully rejuvenated) to ask what measures they have taken. In this case, the control unit 130 may receive the questionnaire results from the information processing device 20 and display them on the display unit 140. This allows the user to know effective anti-aging measures.

[0043] Fig. 7 is a flowchart showing an example of the operation of the portable device 10 in this modified example. In the flowchart shown in this figure, the process up to step S20 is the same as that of the embodiment. Then, after the biometric information acquisition unit 120 acquires the biometric information, the control unit 130 transmits the biometric information acquired by the biometric information acquisition unit 120 or the processing result of this biometric information to the information processing device 20 via the first functional unit 110 (step S36). By multiple portable devices 10 executing this step, the information processing device 20 can generate the above-mentioned statistical data.

[0044] Furthermore, the information processing device 20 transmits the statistical data to the portable device 10. The control unit 130 of the portable device 10 receives the statistical data via the first functional unit 110 (step S37). Then, the control unit 130 causes the display unit 140 to display the statistical data together with the biometric information acquired by the biometric information acquisition unit 120 or the result of processing the biometric information (step S40).

[0045] In addition, if the information processing device 20 already has statistical data, in step S36, the control unit 130 may send information to the information processing device 20 indicating a request for statistical data, instead of sending the biometric information or the processing results of the biometric information.

[0046] Furthermore, as shown in Fig. 8, the processes shown in steps S36 and S37 in this modified example may be performed between step S32 in Fig. 4 and step S40 in Fig. 4. In the example shown in this figure, the mobile device 10 transmits the generated biological information and environmental information to the information processing device 20 (step S26).

[0047] In this modification, when it is necessary to calculate a value indicating the user's health level from the physical property values ​​of the biological information (for example, bone age, skin age, muscle age, or blood vessel age), this calculation process may be performed by the information processing device 20. In this case, the control unit 130 of the mobile device 10 receives the result of the calculation process from the information processing device 20 via the first functional unit 110.

[0048] In this modification, as in the embodiment, the user of the mobile device 10 does not need to perform any operation to acquire biometric information. This reduces the user's effort. The display unit 140 displays the user's own biometric information or the results of processing the biometric information together with statistical data. This allows the user to objectively recognize his or her own health condition. As in the embodiment, processing is performed using only biometric information when the environmental information meets the criteria, so the user's biometric information can be measured with high accuracy. EXAMPLES

[0049] Example 1 FIG. 9 is a plan view of the mobile device 10 according to the first embodiment. FIG. 10 is a cross-sectional view taken along line AA in FIG. 9. In this embodiment, the mobile device 10 is a mobile phone or a smartphone, and has a housing 150. The housing 150 is thin, and has a display unit 140 on its surface. A speaker 160 is provided inside the housing 150. An opening 152 is provided in an area of ​​the housing 150 that overlaps with the speaker 160. The opening 152 is provided to radiate sound from the speaker 160 to the outside of the housing 150. However, if sound from the speaker 160 can be radiated to the outside via the housing 150, the opening 152 does not need to be provided.

[0050] Further, a recess 154 is provided on a side surface of the housing 150. When the user of the mobile device 10 uses the mobile device 10, the user's finger F fits into the recess 154.

[0051] The first electrode 121 and a temperature sensor or humidity sensor of the environmental information acquisition unit 135 are arranged in an area of ​​the side surface of the housing 150 that corresponds to the bottom surface of the recess 154, and the second electrode 122 is arranged in an area of ​​the surface of the housing 150 that is located near the opening 152 (i.e., the area located near the speaker 160). The first electrode 121 contacts the user's finger F, and the second electrode 122 contacts a part of the user's face that is located near the ear. The environmental information acquisition unit 135 acquires environmental information from the finger F. The finger F is, for example, the index finger, but may also be the thumb, middle finger, ring finger, or little finger.

[0052] The arrangement of the first electrode 121 and the second electrode 122 is not limited to the example shown in FIG. 10. For example, as shown in FIG. 20, the first electrode 121 and the second electrode 122 may be arranged at a position where one of the fingers (for example, the index finger) is sandwiched, or may be arranged at a position where different fingers (for example, the thumb and the index finger) touch each other. Also, as shown in FIG. 21, in a case where the portable device 10 has a structure where the user holds it with both hands (for example, a portable game machine, etc.), the first electrode 121 and the second electrode 122 may be arranged at positions corresponding to different hands. In each of the cases shown in FIG. 20 and FIG. 21, a temperature sensor for measuring body temperature of the environment information acquisition unit 135 is arranged near the first electrode 121 or near the second electrode 122. In addition, in a case where the environment information acquisition unit 135 has a clock, a barometer, etc., the clock and the barometer may be arranged at a position different from the first electrode 121 and the second electrode 122.

[0053] In the example shown in Fig. 20, when the environmental information acquisition unit 135 has a temperature sensor, the environmental information acquisition unit 135 may have a heater. In this case, when the detected value of the temperature sensor is less than the reference value (i.e., when the temperature of the user's finger is less than the reference value), the environmental information acquisition unit 135 may turn on the heater to warm the user's finger. Of course, when the detected value of the temperature sensor is much higher than the reference value, it is also effective to cool the finger with a Peltier element or the like.

[0054] 11 is a block diagram showing a functional configuration of the portable device 10. The portable device 10 shown in the figure has the same configuration as the portable device 10 according to the embodiment or the modified example thereof, except that the biological information acquisition unit 120 has a first electrode 121, a second electrode 122, and an impedance calculation unit 123.

[0055] The impedance calculation unit 123 calculates the impedance between the first electrode 121 and the second electrode 122. Then, the impedance calculation unit 123 processes this impedance to calculate at least one of the user's skin age, body water content, and body fat mass.

[0056] In this embodiment, as in the embodiment, the user of the mobile device 10 does not need to perform any action to acquire biometric information. Therefore, the user's effort can be reduced. Also, as in the embodiment, processing is performed using only biometric information when the environmental information satisfies the criteria, so that the user's biometric information can be measured with high accuracy.

[0057] Furthermore, the impedance of the user's body is measured using the first electrode 121 and the second electrode 122. The first electrode 121 is disposed on a side surface of the housing 150, and the second electrode 122 is disposed near the opening 152 of the housing 150. Therefore, the measurement target of the impedance calculation unit 123 is the part of the user's body between the fingertip and the ear. Therefore, since the measurement distance (the distance between two points) is longer compared to the case where the impedance is measured with a finger, the accuracy of the calculation result of the impedance calculation unit 123 is higher.

[0058] Example 2 Fig. 12 is a plan view of the portable device 10 according to the embodiment 2. Fig. 13 is a block diagram showing a functional configuration of the portable device 10 shown in Fig. 12. The portable device 10 according to the embodiment has the same configuration as the portable device 10 according to the embodiment 1, except that the biometric information acquisition unit 120 has a light emitting unit 124, a light receiving unit 125, and a calculation unit 126.

[0059] Both the light emitting unit 124 and the light receiving unit 125 are disposed on the side of the recess 154. The temperature sensor and the humidity sensor of the environmental information acquiring unit 135 are also disposed on the side of the recess 154. The light emitting unit 124 and the light receiving unit 125 may or may not face each other. The light emitting unit 124 emits infrared light toward the finger F. The light receiving unit 125 detects the amount of light reflected by the finger F or the amount of light transmitted through the finger F out of the light emitted from the light emitting unit 124. The amount of light referred to here refers to a change in the volume pulse wave in the case of vascular age, and a change in the absorption wavelength of sugar in the blood in the case of blood glucose level measurement. The calculation unit 126 calculates at least one of the user's vascular age and blood glucose level based on the output of the light receiving unit 125.

[0060] In this embodiment, as in the embodiment, the user of the mobile device 10 does not need to perform any action to acquire biometric information. Therefore, the user's effort can be reduced. Also, as in the embodiment, processing is performed using only biometric information when the environmental information satisfies the criteria, so that the user's biometric information can be measured with high accuracy.

[0061] Example 3 Fig. 14 is a cross-sectional view of the portable device 10 according to the embodiment 3. Fig. 15 is a block diagram showing the functional configuration of the portable device 10 shown in Fig. 14. In this embodiment, the portable device 10 has the same configuration as the portable device 10 according to the embodiment 2, except for the following points.

[0062] First, the mobile device 10 is a watch-type device. The biometric information acquisition unit 120 has an oscillation unit 127 and a vibration detection unit 128. The oscillation unit 127 oscillates ultrasonic waves toward the user's arm A. The vibration detection unit 128 detects the strength or speed of the ultrasonic waves that have passed through the user's arm. The calculation unit 126 calculates the user's bone density (i.e., bone age) using the strength or speed of the ultrasonic waves detected by the vibration detection unit 128. In this embodiment, the operation of the biometric information acquisition unit 120 may be performed at the timing when the mobile device 10 is worn on the user's arm, or may be performed using a timer. In addition, the temperature sensor and humidity sensor of the environmental information acquisition unit 135 are provided on the inner surface of the mobile device 10 (i.e., the surface in contact with the arm A).

[0063] In this embodiment, as in the embodiment, the user of the mobile device 10 does not need to perform any action to acquire biometric information. Therefore, the user's effort can be reduced. Also, as in the embodiment, processing is performed using only biometric information when the environmental information satisfies the criteria, so that the user's biometric information can be measured with high accuracy.

[0064] In addition to measuring bone density, the watch-type device shown in this embodiment can also measure the body impedance described above, and measure vascular age or blood glucose level using infrared rays, and these may be combined as appropriate.

[0065] Example 4 16 is a block diagram showing a functional configuration of the portable device 10 according to Example 4. In this example, the portable device 10 has the same configuration as the portable device 10 according to Example 2, except that the portable device 10 has a pedometer 129 instead of the light-emitting unit 124 and the light-receiving unit 125.

[0066] The calculation unit 126 has a built-in timer. Using the number of steps detected by the pedometer 129 and the timer, the calculation unit 126 calculates the number of steps taken by the user per unit time. The calculation unit 126 outputs the number of steps to the control unit 130. The calculation unit 126 may calculate the walking speed of the user by multiplying the calculated number of steps by the stride length. Here, the stride length is stored in advance in the calculation unit 126. The control unit 130 can calculate the muscle age of the user based on the number of steps and walking speed of the user in a day.

[0067] In this embodiment, as in the embodiment, the user of the mobile device 10 does not need to perform any action to acquire biometric information. Therefore, the user's effort can be reduced. Also, as in the embodiment, processing is performed using only biometric information when the environmental information satisfies the criteria, so that the user's biometric information can be measured with high accuracy.

[0068] (Reference example) 17 is a block diagram showing a functional configuration of a portable device 10 according to a reference example. In this reference example, the portable device 10 has a similar configuration to that of the portable device 10 according to the fourth embodiment, except that the portable device 10 has an input unit 170 instead of the calculation unit 126 and the pedometer 129.

[0069] In this reference example, the portable device 10 has a game function. The input unit 170 is a portion where the user performs input to the portable device 10. The control unit 130 determines the brain age of the user of the portable device 10 based on the input timing to the input unit 170, etc. The control unit 130 may perform a specific display on the display unit 140, and determine the brain age of the user based on the input timing to the input unit 170 in response to this display.

[0070] According to this reference example, the brain age of the user can be determined.

[0071] Example 5 In this embodiment, the biometric information acquiring unit 120 of the mobile device 10 has at least two of the functions shown in the first to fourth embodiments and the reference example. Therefore, the biometric information acquiring unit 120 can acquire multiple types of biometric information. Then, the mobile device 10 performs the following process based on the measurement results of these multiple functions.

[0072] 18 and 19 are flow charts for explaining the functions of the mobile device 10 in this embodiment.

[0073] FIG. 18 shows the operation when the user uses the mobile device 10 for the first time. First, the biometric information acquiring unit 120 of the mobile device 10 acquires multiple types of biometric information (step S110). The biometric information acquiring unit 120 processes the acquired biometric information as necessary. The control unit 130 generates data for displaying the biometric information acquired by the biometric information acquiring unit 120 or information indicating the processing result thereof (step S120), and causes the display unit 140 to perform display using this data (step S130). This display includes multiple pieces of biometric information or the results of processing this biometric information. For example, this display includes at least two of bone age, skin age, muscle age, blood vessel age, and brain age. The displayed biometric information or the processing result thereof is stored in the control unit 130.

[0074] Based on the results displayed on the display unit 140, the user selects an item that the user wishes to improve (at least one of bone age, skin age, muscle age, blood vessel age, and brain age) and inputs the selection result (step S140). The control unit 130 searches for ingredients and habits that will improve the selection input in step S140, and displays the search results (step S150). The search range may be within a storage medium that the mobile device 10 already has, or may be an external server (for example, the information processing device 20 shown in FIG. 3).

[0075] FIG. 19 shows the operation when the user uses the mobile device 10 for the second or later time. The processes in steps S110 and S120 are the same as the example shown in FIG. 18. Then, the control unit 130 reads out the past measurement results or processing results (step S122), and displays the read results on the display unit 140 together with the newly measured measurement results or their processing results (step S130). After that, the user selects an item that he or she wishes to improve (at least one of bone age, skin age, muscle age, blood vessel age, and brain age) based on the results displayed on the display unit 140, and inputs the selection result (step S140). Then, the control unit 130 again searches for ingredients and habits to improve the item currently selected by the user, and displays the search result (step S150).

[0076] 18 and 19, when searching for ingredients and habits for improving the selected subject input in step S140, the external server may preferentially select ingredients and habits whose effectiveness has been verified by other users. This verification may be based on, for example, the results of a questionnaire given to users.

[0077] According to this embodiment, the mobile device 10 can present ingredients and habits for improving an item that the user wants to improve.

[0078] Although the embodiment and examples have been described above with reference to the drawings, these are merely examples of the present invention, and various configurations other than those described above can also be adopted. [Explanation of symbols]
